METHODS: Web of science, PubMed, Scopus, Google Scholar, Embase, and Cochrane library were systematically searched up to August 2023. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and Problem/Population, Intervention, Comparison, and Outcome (PICO) guidelines were used. Two authors independently reviewed the eligible articles and assessed the quality of them.
RESULTS: In total, 15 studies including 16144 patients met the inclusion criteria. Ten studies reported the relation of BPPV to monthly mean temperature, 7 to monthly average humidity, 4 to monthly average rainfall, 6 to monthly sunlight time, and 2 to average solar radiation. The incidence of BPPV was associated significantly with atmospheric pressure (P: 0.003) and rainfall (P: 0.017). However, there was not any statistically significant correlation between incidence of BPPV and humidity, sunlight time, temperature, and solar radiation level (P > 0.05).
CONCLUSIONS: The incidence of BPPV was higher in cold months of a year in both northern hemisphere and southern hemisphere countries. Although it can be because of negative correlation with temperature, the current meta-analysis did not find any statistically significant negative correlation with temperature. In addition, the incidence of BPPV was associated significantly with atmospheric pressure (positive correlation) and rainfall (negative correlation).
方法:Webofscience,PubMed,Scopus,谷歌学者,Embase,和Cochrane图书馆进行了系统搜索,直到2023年8月。系统评价和荟萃分析(PRISMA)和问题/人口的首选报告项目,干预,比较,并使用结果(PICO)指南。两位作者独立审查了合格的文章并评估了它们的质量。
结果:总计,包括16144名患者在内的15项研究符合纳入标准。十项研究报告了BPPV与月平均温度的关系,7至月平均湿度,4至月平均降雨量,6至每月日照时间,和2平均太阳辐射。BPPV的发生率与大气压力(P:0.003)和降雨(P:0.017)显着相关。然而,BPPV的发生率与湿度之间没有任何统计学上的显着相关性,阳光的时间,温度,和太阳辐射水平(P>0.05)。
结论:在北半球和南半球国家,一年中寒冷月份的BPPV发病率较高。虽然这可能是因为与温度呈负相关,目前的荟萃分析未发现与温度有统计学意义的负相关.此外,BPPV的发生率与大气压(正相关)和降雨(负相关)显着相关。
